I have trained my kitty to be around my birds (2 guineas, 3 pea fowl, and 2 chickens) ... At first they would eye each other from the other side of the glass windows and doors. Now I put kitty on the lead, and leave him outside, where the birds come up to him. Sometimes the birds or kitty will...
I'm thinking of getting two more chooks ... it is only two of us at home, so I may approach the neighbour (who does not have any) and ask her whether she woulc like eggs, and in exchange, if she will keep her scraps for me : )
Wow! well done ... I wish I were in a position to do what you have just done ... the earthworks has been done, and then the tunnel framework to be dismantled and relocated, garden beds, trellises etc : )
